COATING GLAZINGr-BARS AND OTHER IMPLEMENTS VJITH LEAD OR GTHER PROTECTIVE METAL.

Aplication filed April 12, 1915.

To all whom it may concern: I

Be it known that we, Ennusr ALEXANDER CLAREMONT and JOHN STRATTON, both sub jects of the United Kingdom of Great Britain and Ireland, and residing, respectively, at High Legh and Bowdon, in the county of Chester, and CHARLES SANDELL FARMER, subject of the 'United Kingdom of Great Britain and Ireland, residing at Salford, in the county of Lancaster, all in Eng land, have invented certain new and useful Improvements in Coating Glazing-Bars and other Implements with Lead or other Protective Metal, of which the following is a specification. 4

This invention relates to the manufacture of lead and other metal pipes by the process of extrusion to form the protective covering of glazing bars and other articles and has for its object to form a solid bar of lead or other metal at the will of the operator in lieu of the hollow pipe or sheath without otherwise disturbing or stopping the operation of the press.

This invention is useful in the manufacture of lead sheathed glazing bars and where and die may be drawn apart and replaced at the will of the operator without disturbing the press. With a press so constructed when the glazing bar or other aricle is passing through same and the rear end of said bar has passed out of or is about to pass out of the core, by drawing apart the core and die a solid bar of lead or other metal is formed on the rear end of and in continuation of the glazing bar or other article and when a sutlicient length of said solid bar has been formed, the core can be replaced in its former position andanother glazing bar or article treated. The movement of the core is effected by the elements of an additional or subsidiary hydraulic press preferably connected to the lead press, whereby the core can be forced forward or Specification of Letters Eatent.

backward within such limits and at such speed as may be desired. Similarly the die can be made to move forward and backward Fig. l is a detail view showing the ends of two bars which have been lead coated in the press and the solid bar of lead between 7 them. Fig. 5 is a vertical longitudinal section through the core-box. Fig. 6 is a plan view of the lower half of said core-box. Fig. 7 is a vertical cross section of the core-box, on the line 77 of Fig. 5. Fig. 8 is a cross section of the subsidiary hydraulic press, on the line 88 of Fig. 2. Fig. 9 is a sectional elevation showing a modified form of apparatus in which the subsidiary hydraulio press is applied to the die side of the discharge opening.

In all. the figures the same reference characters designate the same parts.

With reference to Fig. 1, A is the main frame of the lead press, B the main hydraulic ram, C the lead container, D the core box, E the additional or subsidiary hydraulic press, F a steel bar entering the press to be sheathed and G the said bar which has been lead coated leaving the press.

Referring to Figs. 2 to 7, H is the core held centrally in a sleeve H in the core-box D and held in position by the ram I of the additional or subsidiary hydraulic press E. H designates the die held in the corebox by means of an apertured threaded plug H, K is the water chamber of the sul sidiary hydraulic pre a and K is the water feed pipe to the same. The core box D as is usual is constructed in two halves horizontally D D Figs. 5 and 7 to permit (by removing the uppep half D access to the inte ior, the two halves when in position be ing secured together by bolts D An opening 0 in the upper half of said box receives the lead from the container and is provided with a wall or partition P approximately representing in cross section an inverted V dividing the opening into two channels V and V L he said opening at the upper part is outwardly flared as shown at l and lower d wn-the sides S of each oi? the two chanare sloped to direct the flow f lead in the desired directions as indicated by the broken curved lines i1 Fig. 3 and in Fi '7 The method of operation is a Hows:- The steel bars F are successively passed through the hydraulic ram 1 which is made hollow to receive them, thence into the hollow core H and through the die H a predetermined distance being lelt between said bars, the latter being covered with lead at the no at M. As the forward end of each bar in its passage through the apparatus reaches the nose of the core H the ram I and the core are aovanced into the posltlon shown by full lines in Fig. 2 by hydraulic pressure applied through the feed pipe K in the chamber K. and are held in this posi tion until. the rear end of the bar has reached the point M Fig. 2, whereupon by means of a suitable valve (not shown) automatically or otherwise operated the hydraulic pressure in the chamber K is suddenly released. As soon as the pressure is released from the chamber K the pressure of the lead on the nose of the latter forces back the core H in the sleeve H and also the hydraulic ram is formed a solid bar of lead N (Fig. l)- of v the same cross section as the coated bar, the coatings and bars or lead being homogeneous. The movable part of the additional or subsidiary hydraulic press and the core may -e moved both backward and forward by hydraulic pressure. As shown in Fig. 9,

' we may also apply the hydraulic ram 1 of the subsidiary press E? to the die side of the core box D and move the die H instead oi the core H in the same manner, or,

as will be readily undcrstooo, we may move 1 both the die and the core by providing a hydraulic ram for each of them. The core H operates in the sleeve H. As the bars are received from the apparatus they are sawed apart through the solid bars N of Copies of this patent may be obtained for lead thus producing bars coated throughout with lead homogeneously without the necessity of sealing the ends; it is not new to cover the ends of lead coated glazing bars-with lead by plumbing. or otherwise fastening on caps or end pieces all of which operations involve apart from 5 the cost involve a rislr of defects but so far as we are aware it is novel to cover the ends oi the bar homogeneously with the actual coating.

lVhat claim as our invention and desire to secure by Letters Patent of the United States is:-

1. The combination of a hydraulic lead press, adapted to receive articles to be coated,

a co-actin core and die in said press adapted to extrude a pipe to form a metal coating for said articles, and means for causing a relative movement of said core and die, whereby between adjacent articles a solid irass of metal is produced homogeneous with said coating.

The combination of a hydraulic lead press, adapted to receive articles to be coated, a core be? therein to receive molten metal, a co-acting core and die in said corebox, adapted to extrude a pipe to form a metal coating for said articles, an auxiliary hydraulic press and means operated thereby to cause a relative movement of said core and die for the purpose of producing be tween adjacent articles a mass of metal 99 homogeneous with said coating.

3. The combination of a hydraulic lead press, adapted to receive glazing bars to be coated, a core-box therein to receive molten lead, a die and hollow core co-acting therewith disposed in said core-box, and adapted to EXtlUd a pipe to form a lead coating for id bars, an additional hydraulic press, a sin in the latter and means for actuating .id ram to cause a. relative movement be- 100 "*een said core and die, whereby between cdjaccnt bars a solid mass of lead of the same cross section as the bars is produced, homogeneous with said coating, and form ing an end covering for said bars.

In witness whereof we have signed this specification in the presence of two witnesses. 7
